OS X/iOS: If you have a relatively recent Mac and an iPhone, iPad, or Apple Watch equipped with TouchID, Apple’s fingerprint-reading security feature, MacID lets you turn your mobile device into a key that can unlock your Mac—when you’re nearby and want to use it, of course.

The Virginia Circuit Court ruled this week that you don't have to give up your passcode to police if you're detained. That's great news, but apparently fingerprints are a different story, so if you have Touch ID enabled, you could still be forced to unlock your phone.

The iPhone 5s has a handy Touch ID sensor where you can scan your finger to unlock your phone. It's great when it works, but for some people it's not working all the time. If you're struggling with it, Macworld's put together a guide for getting the best scans of your fingers so they'll actually unlock your phone.
